Police advised visitors to the park to walk with a friend, be aware of surroundings and call 911 immediately if you see a suspicious person, and don't wait until you get home. If possible, write down vehicle license plates.

When listening to music with headphones, leave one headphone off or leave it at a low volume to hear someone walking up behind you, police said.

Anyone with information about the park incidents should send an email to the Euless police department at kmeador@eulesstx.gov
